About the Environmental Laboratory Accreditation Program (ELAP)

  • Information on the new CA ELAP Fees – April 15, 2021

New Fee Structure
A new fee structure became effective on January 1, 2021 as part of the new California Environmental Laboratory Accreditation Program Regulations. 

Renewal Application Fee and Annual Accreditation Fee
Each laboratory is required to pay a nonrefundable renewal application fee at the time of submittal of the application, and an Annual Accreditation Fee one year from the date of issuance of accreditation. The fee is composed of the following components.

  • Base fee – paid by all laboratories. $2,500
  • Per Field of Accreditation (FOA) fee – paid by all laboratories. Count the number of individual subgroups in the Field(s) of Accreditation Tables for which you are seeking accreditation to determine which Tier applies. You do not have to pay the fees for any Tiers falling outside of the one that applies to your laboratory (i.e. only select one Tier price in the table below).
  • Reciprocity fee – paid by all out-of-state laboratories. $5,000  


Fee Component


Base Fee (all laboratories)


Reciprocity Fee (Out-of-State Laboratories only)


Field of Accreditation (FOA) Fee (select only one tier)


Tier 1 – 1-10 FOAs


Tier 2 – 11-49 FOAs


Tier 3 – 50-99 FOAs


Tier 4 – 100-149 FOAs


Tier 5 – 150-249 FOAs


Tier 6 – 250-349 FOAs


Tier 7 – 350+ FOAs



Application Late Fees
Late applications will be subject to a 15% late fee if received after the application deadline but before the expiration date of your certificate. Any application received after the expiration date of a certificate will be subject to a 30% late fee.

IMPORTANT: An on-time application may still be assessed a late fee if it is incomplete and requires ELAP to follow up for additional documentation beyond your application deadline. Be sure to submit all the required components of a complete application package as defined in California Code of Regulations § 64802.00 to avoid being charged a late fee.

Assessment Fees
Laboratories using ELAP to perform an assessment will be charged the following assessment fees. The Water Boards will send a notice that the assessment fee is due once it has been scheduled. Do not combine your assessment fee with a renewal or annual fee.

Initial and Renewal Assessments

  • Main laboratory - $5000
  • Satellite or mobile laboratory - $2500 each
Amendment Assessments
  • Addition or reinstatement of Field(s) of Accreditation - $1000
  • Addition of a satellite or mobile Laboratory - $2500 each
  • Change in laboratory location - $5000

Courtesy Notices
While we aim to provide a laboratory a courtesy notice approximately 90 days before a renewal application or annual accreditation fee is due, any notice sent by ELAP is a courtesy on behalf of the program and should not be the only mechanism a laboratory has in place to prompt the submission of an application

  • Sign up for the TNI Documentation Workshop!

  • California Environmental Laboratory Accreditation Program (ELAP) has opened registration for fourteen sessions of the 2016 TNI Quality System Documentation Workshop in partnership with A2LA Workplace Training. Register here today!

    The workshop runs from 10:00 am – 3:00 pm (PT) with a break from noon to 1:00 pm on both days. This is a standalone training and you only need to register for one session. Only one person from each accredited laboratory may sign up. But don’t worry – we are recording the training and will post it on our website in the future so that everyone can watch.

    “The TNI Documentation Training session was truly helpful, especially since our laboratory is at the start of our TNI transition. It opened our eyes on how to “read and understand” the TNI Standard, making it easier to set up the fundamental cornerstones aiding us with a smoother transition into TNI.”

    What will you learn?
    This virtual workshop is an 8-hour overview of the 2016 TNI Standard Quality System requirements that provides all the materials you need to create a quality system for your laboratory. Class sizes are capped at 30 students per session to allow for interaction and discussion with the expert instructor and your classmates.
    You will receive the following learner materials when you register. Attendees should perform at least a brief review of the materials and note any questions you have before coming to the training.

    • Templates: Fillable templates for 14 policies and procedure (Volume 1, Module 2) that can be directly implemented in your laboratory.
    • Requirements & Explanations: An extensive document describing the requirements, explanations, and context for key areas of the Standard with which accredited laboratories have historically struggled. They also include potential solutions your laboratory can customize for itself.
    • Examples of Policies & Procedures: Compliant and non-compliant policies and procedures are provided with explanations for why they do or do not comply with the 2016 TNI Standard. At least 3 compliant examples are provided for each clause covered in the course to help your laboratory implement a solution that best suits your processes.
    • Job Aid: A “quick-look” tool that can be used immediately in your laboratory to identify where the TNI Standard requires policies, procedures, and records. It can function as a quick checklist to ensure your laboratory complies.

    Is there anything else I need to know?
    Take advantage of two Zoom breakout rooms during lunch each day! “Ask the Instructor” will be hosted by the trainer to answer TNI Questions, and “Ask ELAP” will be hosted by an ELAP staff member to answer ELAP-related questions.

What does ELAP do?

ELAP provides evaluation and accreditation of environmental testing laboratories to ensure the quality of analytical data used for regulatory purposes to meet the requirements of the State's drinking water, wastewater, shellfish, food, and hazardous waste programs. The State agencies that monitor the environment use the analytical data from these accredited laboratories. The ELAP-accredited laboratories have demonstrated capability to analyze environmental samples using approved methods.

Program Overview

The California Environmental Laboratory Improvement Act (Assembly Bill 3739, Chapter 894, Statutes of 1988) took effect on January 1, 1989. It established a consolidated fee-supported accreditation program for environmental health laboratories, and a special fund, the Environmental Laboratory Improvement Fund, to support the program. Under the Act, accreditation is required of an environmental laboratory for producing analytical data for California regulatory agencies. The data is used to demonstrate compliance with requirements of drinking water, wastewater, food for pesticide residues, shellfish testing, and hazardous waste sections of the California Health and Safety and Water Codes. The Environmental Laboratory Accreditation Program (ELAP) is responsible for implementing the Act.

ELAP is part of the Division of Drinking Water at the State Water Resources Control Board and is overseen by Chief Christine Sotelo. ELAP’s staff and functions are divided between three locations - Sacramento, Glendale, and Richmond. The Sacramento location is ELAP’s headquarters and is home to the Program Development, Research, and Enforcement Unit (PDREU). The PDREU is responsible for all program transformation initiatives, technical research, and enforcement cases. The Glendale Field Office is ELAP’s Assessment Unit with a group of specialized auditors. The Richmond Field Office houses the Monitoring Unit responsible for the evaluation of annual proficiency testing results. ELAP staff in all offices work together across geographic boundaries to fulfill the duties prescribed by the Laboratory Improvement Act: Inspect, Accredit, Monitor, and Enforce.
